HANDLE DEVICE FOB-SWITCHES.

Application filed July 10,

To all whom it may concern:

Be it known that I, NILs J. A. WVAHLBERG, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Handle Devices for Switches, of which the following is a specification.

My invention relates to switches and particularly to handles therefor.

The object of my invention is to provide a device of the above-indicated character that shall be rugged and durable in construction and inexpensive to manufacture.

In practicing my invention, I provide a switch handle comprising a molded grip member of insulating material and a metal shank or supporting member therefor that shall be so formed of fiat or strap metal as to prevent removal of the grip member and that materially lowers the cost of the device and the labor of constructing the same.

Fig. 1 is a side elevational view of a knifeblade switch embodying my invention; Fig. 2 is a developed elevational view of a portion of the same; Fig. 3 is a view, partially in section and partially in plan, of one end of a switch blade.member to which a handle is attached; and Fig. 4: is an elevational view taken at right angles to the device shown in F i 3.

A knife-blade switch 1 of a usual construction embodies, in general, an insulating base member 2 of slate or other suitable material, stationary contact members 3 and 4, a

knife-blade member 5 pivoted to the member 3 and a grip or handle member 6. The memher 6 is provida with acentrally disposed metal shank 7 having integral projections 8 and enlarged end members 9 that are perforated for the reception of pins 10 for attaching the same to the member 5. As shown in Fig. 2, the member 7 is initially of flat metal, punched or otherwise constructed to the shape shown, in which the projections 8 are integrally formed thereon. The member 7 is folded over upon itself at an intermediate point, which is indicated by the dotted line wa, (Fig. 2) to form a single longitudinal member having adjacent body portions and separated ends as indicated in Fig. 3. After the member 7 is folded, the grip member 6 is molded thereon.

Specification of Letters Patent.

1918. Serial No. 244,273.

The enlarged ends 9 of the member 7 register after folding and may be separated, as best shown in Fig. 3, for embracing engagement with the end of the blade 5 to which the member 7 may be rigidly attached by rivets 10 or other suitable means.

While I have shown and described one form of my invention, changes may be made therein without departing from the spirit and scope thereof, as set forth in the appended claims.

I claim as my invention:

l. A handle device comprising a longitudinal member folded end-to-end to permit the ends thereof to constitute gripping jaws, a member secured between the said jaws and a grip member disposed over the folded portion of the same.

2. A handle device comprising a member folded end-to-end to form a pair of substantially co-extensive arms, one end of the pair being imbedded in a grip member and the other end thereof being formed to serve as gripping jaws for attachment to a supporting member.

3. A handle device comprising a pair of substantially co-extensive arms, one end of the pair being formed to serve as gripping jaws, and a grip member disposed about the other end thereof.

4. In a handle device, the combination with a grip member of molded material and a supporting member therefor, of means embedded in said material for connecting said members comprising an initially-flat metal member having interrupted-surface means for holding it to-said material, said member being intermediately bent over upon itself to permit its opposite end portions to constitute co-operating holding means to receive said supporting member.

5. A handle device comprising a grip member of molded material and a transversely-folded longitudinal supporting member embedded therein having interruptedsurface means for holding it to said molded material. and its free ends projecting therefrom.

In testimony whereof, I have hereunto subscribed my name this 29th day of June 1918.
